I guess I have been having some and not realizing it either! Our midwife did a home visit last night and when she was feeling around to check baby's position, she said she felt a BH. I was like, really?? lol I think I had a few during the night too when I rolled over, it felt tighter than normal. I think I always just assumed it was gas or a weird baby movement rather than a BH.
Anyways, she's been having a hard time getting a lock on baby's position the past few times, and thinks she might be sideways right now I'm going to have an u/s to check position hopefully next week. The only good thing is she is still small and has room to move/change positions still!
